Received changes through RFC Editor sync (created alias RFC 8460, changed abstract to 'A number of protocols exist for establishing encrypted channels between SMTP Mail Transfer Agents (MTAs), including STARTTLS, DNS- Based Authentication of Named Entities (DANE) TLSA, and MTA Strict Transport Security (MTA-STS).  These protocols can fail due to misconfiguration or active attack, leading to undelivered messages or delivery over unencrypted or unauthenticated channels.  This document describes a reporting mechanism and format by which sending systems can share statistics and specific information about potential failures with recipient domains.  Recipient domains can then use this information to both detect potential attacks and diagnose unintentional misconfigurations.', changed pages to 34, changed standardization level to Proposed Standard, changed state to RFC, added RFC published event at 2018-09-26, changed IESG state to RFC Published)
